Database Development Jobs

I need an Oracle APEX application that streamlines one of our internal business processes from start to finish. The focus is a clean, permission-based workflow that automatically routes each new record through a multistep approval cycle. At a minimum the app must: • Capture data through responsive APEX forms • Trigger an approval workflow the moment a record is submitted • Update status, log every decision, and prevent users from skipping steps When an approver acts, the system should move the item to the next stage, send the correct email or in-app notification, and maintain an audit trail we can export to CSV or view in a dashboard. I will provide table definitions and sample data; you’ll translate that into APEX pages, processes, and any PL/SQL packages req...

I’m kicking off a new healthcare patient-management system and the first critical piece is a rock-solid, compliant data layer. The entire scope at this stage revolves around database management—designing, building, and documenting a schema that can safely house patient records, appointments, clinical notes, and billing details while meeting HIPAA-level security expectations. Here’s what I need from you: • Analyse typical patient-care workflows and translate them into an efficient relational model. • Deliver an ER diagram, a fully normalised schema, and an indexing strategy suitable for high-volume queries. • Implement the model in the SQL engine you recommend (PostgreSQL, MySQL, or MS-SQL are all fine if they cover encryption-at-rest, robust backup, a...

The MVP should be scalable, secure and designed so additional pet-care service categories can be added in future versions. I am looking for someone with proven experience in marketplace, booking or service-platform applications. Please provide examples of similar projects you have dev...

User Interaction: The application should be designed for manual data entry within the app. Users should be able to input data for the certificates ...

I need a purpose-built IoT inventory platform that keeps every tool in my auto shop accounted for and instantly searchable from a tablet on the workshop floor. The interface has to feel at home on an iPad or similar device—large touch targets, quick loading times, and an offline-tolerant design so my technicians can still work if Wi-Fi drops for a moment. Core workflow Technicians will scan or tap a tagged tool, confirm where it is going, and the system updates our stock level and location log. When a tool hasn’t been returned or its quantity falls below a preset threshold, the platform should flag it on the dashboard and optionally push a notification. I’m open to common tag technologies such as BLE or passive RFID; the software just needs a clean way to map tag IDs to ...

I’m looking for a developer who can create a purpose-built platform that lets me run every aspect of my construction projects from one place. The core of the system has to make life easier for two distinct roles—project managers and site workers—so role-based dashboards and permissions are essential. The platform must, at a minimum, include: • Task tracking so crews always know what’s next and I can see progress in real time. • Budget management with live cost vs. budget comparisons. • Resource allocation to coordinate labour, plant and materials without clashes. • A clear scheduling layer that ties tasks, resources and deadlines together. I need a clean, intuitive interface that works on desktop and mobile browsers, solid back-end archit...

I am looking for a development partner to deliver a specific, well-defined feature (detailed in Sections 4–6), and ongoing relationship covering infrastructure maintenance and continued application development. This document is both a technical brief and a request for proposal.

About This Engagement The product is a property monitoring platform: sensors installed in a property (temperature, humidity) feed a data pipeline that assesses damp, mould, and thermal risk, and generates reports for landlords and tenants. The work described here adds a new UI-driven workflow for triggering those re...

I need a straightforward, standalone two-tier MLM system that will sell a single $9 product. The core of the job is to let every buyer automatically become an affiliate, earn on two levels, and see exactly what is happening with their network and commissions. Scope of work • Referral tracking – unique links or codes generated at sign-up and logged through to purchase on both levels. • Commission calculation – automatic, tier-based payouts that I can adjust from an admin panel. • User dashboard – clean, mobile-friendly view of referrals, sales, and earned commissions, plus the ability to copy their link. It can be custom-built or use an off-the-shelf framework if that speeds things up; the system simply needs to run on its own server without tying in...

I need a solid PostgreSQL-backed RESTful API to drive the Solar TwinPro web application. Your task is to design the database schema and expose clean, versioned endpoints that cover full CRUD functionality for each core resource in the system. The web front-end will consume JSON, so consistent status codes and clear error handling are important. Please structure the project so it can be deployed easily (Docker preferred, but I am open to other simple approaches) and include concise documentation; an OpenAPI/Swagger spec is ideal so the front-end team can plug in without guesswork. Deliverables • PostgreSQL schema (DDL) and seed data • REST endpoints covering create, read, update, delete for all defined entities • Environment and run instructions (e.g., Dockerfile or...

I’m looking for a straightforward app built on Emergent that lets our employees key data into a 14-column table, search or filter any of those fields on demand, and immediately view the results in an interactive dashboard. Here is what matters to me: • A clean, employee-friendly data-entry screen with validation for each of the 14 columns (I’ll supply the exact field names and rules once we start). • A query function—simple text or drop-down filters are fine—that can pull records instantly. • An interactive dashboard generated from the same dataset so staff can spot trends without exporting to Excel. You’re free to organise the underlying database as you see fit so long as every column remains searchable and the whole solution stays ...
